1 Reporting standards for American Indian/Alaska Native 12th-graders were not met; therefore, data for this group are not shown in the figure.2 Total includes other racial/ethnic groups not shown separately in the figure.
NOTE: NAEP achievement levels define what students should know and be able to do. Proficient represents solid academic performance. Students reaching
this level have demonstrated competency over challenging subject matter. NAEP reports data on student race/ethnicity based on information obtained
from school rosters. Separate estimates for Asians and Native Hawaiians/Pacific Islanders were not available. Race categories exclude persons of Hispanic
ethnicity.
